NAME

       _U_dyn_cancel -- cancel unwind-info for dynamically generated code

SYNOPSIS

       #include <libunwind.h>

       void _U_dyn_cancel(unw_dyn_info_t *di);

DESCRIPTION

       The  _U_dyn_cancel() routine cancels the registration of the unwind-info for a dynamically
       generated procedure. Argument di is the  pointer  to  the  unw_dyn_info_t  structure  that
       describes the procedure's unwind-info.

       The  _U_dyn_cancel()  routine is guaranteed to execute in constant time (in the absence of
       contention from concurrent calls to _U_dyn_register() or _U_dyn_cancel()).

THREAD AND SIGNAL SAFETY

       _U_dyn_cancel() is thread-safe but not safe to use from a signal handler.
